(-)-(1S,3S,5R,6S,8R,10R)-Trishomocubanethanoic acid (5) of known absolute configuration and absolute rotation was converted into (+)-(1S,3S,5S,6S,8R,10R)-2-bromoethynyl-D3-trishomocubane (27) of C3 symmetry. 1,3,5,7-Tetraethynyladamantane (22), with Td symmetry, was prepared from 1,3,5,7-tetrakis(hydroxymethyl)adamantane(13). Coupling of the C3-component 27 with the Td component 22 was successfully
(-)-(1 S,3 S,5 R,6 S,8 R,10 R)-已知绝对构型和绝对旋转的三茂铁金花酸(5)被转化为(+)-(1 S,3 S,C 3对称性的5 S,6 S,8 R,10 R)-2-溴乙炔基-D 3-三茂铁(27)。1,3,5,7- Tetraethynyladamantane(22),与Td的对称性,由1,3,5,7-四(羟甲基)金刚烷(制备1 3)。C 3组分的偶联27Td组分22通过Chodkiewicz和Cadiot的方法成功完成,提供(+)-1,3,5,7-四[2-(1 S,3 S,5 R,6 S,8 R,10 R)- D 3 -trishomocubanylbuta-1,3-diynyl] adamantane(4)可获得的最高静态和时均动态对称性分别为T和(C 3)4 XXXT。
